摘要
目的 :对黄蜀葵花 (AbelmoschusmanihotL Medic)总黄酮进行化学成分的研究。方法 :利用色谱和分部结晶方法进行成分分离 ,根据物理化学性质和波谱学手段对化合物进行结构鉴定。结果 :分离到 4个黄酮醇单糖苷 ,分别鉴定为棉皮素 3′ O β 葡萄糖苷 (Gossypetin 3′ O β glucoside ,1) ,异槲皮苷 (Isoquercetin ,2 ) ,金丝桃苷 (Hyperoside ,3)和槲皮素 3′ 葡萄糖苷 (Quercetin 3′ glucoside ,4 )。结论 :其中 1为新化合物 ,2为从该植物中首次分得。
AIM:To study the total flavonol constituents of Abelmoscchus manihot L. Medic. METHOD:The chemical constituents were isolated by the chromatographic and crystal techniques, and their structures were identified by the physical and chemical properties especially by the spectral analysis. RESULT: four flavonol monoglycosides were obtained and they were identified as gossypetin-3′- O -β-glucoside (1), isoquercetin (2), hyperoside (3) and quercetin-3′-glucoside (4). CONCLUSION: compounds 1 and 2 were obtained from the Abelmoschus manihot L. Medic for the first time, and compound 1 was a new compound.
